IMPRQVEMENT EN RESERVQIR COOKlNG-STQVES.

Specification forming part of Letters Patent No. 1163,157, dated May 11,1875; application filed April 14, 1875.

(Lisa 1.

To all whom it may concern Be it known that we, ALBERT O. Consn andMICHEL G. FAGAN, of Troy, in the county of Rensselaer, and in the Stateof New York, have invented certain new and useful Improvements inReservoir Cooking-Stove; and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, making a part of this specification, in whichFigure 1 is a plan view of the upper side of our improved stove, withthe top plate removed. Figs. 2, 3, and 4 are vertical sections fromfront to rear, upon lines 00 x, y y, andzz. respectively, of Fig. 1.Fig. 5 is a cross-section upon line a z of Fig. 1, and Fig 6 is a likeView upon line 2 z of same figure.

Letters of like name and kind refer to like parts in each of thefigures.

The design of our invention is to render the operations of heating theoven and waterreservoir of a cooking-stove more fully under control thanhas heretofore been practicable; and to this end it consists,principally, in combining with the descending and ascending fines of atwo-flue cooking-stove, which are located between the oven and thecasing of a water-reservoir, and at their upper ends communicate throughdampered openings with the top oven-flue, and at their rear sides with asheet-flue beneath said reservoir, a third vertical flue, which extendsbetween said top oven-flue and said reservoir-flue, substantially as andfor the purpose hereinafter specified. It consists, further, in thecombination of the descending and ascending flues with their damperedopenings, with the top ovenflue and reservoir-flue, substantially as andfor the purpose hereinafter shown. It consists, finally, in thecombination of the descending, ascending, top oven, reservoir, andsupplemental fines, substantially as and for the purpose hereinafter setforth.

In the annexed drawing, A represents the bottom plate, B the top plate,0 and 0 the side plates, and D therear end plate, of a cooking-stove,having an oven, ,E, top and bottom oven-fines F and G, respectively, and

between said oven and rear end plate a descending and an ascending flue,H and I, respectively. Secured to or upon the outer side of the endplate D is a casing, K, for the reception of a water-reservoir, L, whichcasing embraces closely the sides and ends of the same, but has asomewhat greater depth, so as to leave between their respective bottomsa sheet-fine, M. As seen in Fig. 6, the tines H and I at their upperends have each onethird the transverse dimensions of the stove, and arearranged so as to bring said descending fine H at one side, and saidascending flue at the center of said stove, which arrangement iscontinued downward to the bottom of the casing K, from whence the plateH, that separates said flues, inclines toward the transverse center ofthe stove, so that at the bottom of the same they divide the spaceequally. Between the ascending flue I and the lefthand side of the stoveis a space, N, which corresponds in horizontal dimensions to the likefeature of said flue, is open at its upper end, and at its lower end,upon a line with the bottom of the reservoir-casing K, is inolosed bymeans of a horizontal flue-strip, n. An opening, a, in the end plateD,corresponding in vertical dimensions to the sheetfiue M, affordscommunication between the latter and the space or flue N. Within thefront side of the descending flue H, above the top oven-plate e, isprovided an opening, h, which is inclosed, when desired, by means of asliding damper, h, while a similar opening, i, within the front of theascending flue I, is inclosed by a rolling damper, i. Between thesheet-flue M and the fines H and I are provided openings h and t',respectively, the latter of which is inclosed, when desired, by means ofa rolling damper, i, that is hinged at its lower edge. Two verticalflue-strips, P and P, extending rearward within the sheetflue M from theends of the opening t', complete the invention, the operation of whichis as follows:

When fire is first started the damper t" is turned downward, so as toadmit the gaseous products of combustion directly to the exitflue, butat all other times is kept closed.

When it is desired to heat the oven, but not the reservoir, the dampersi and i are closed and the damper h opened, by which means the heatedgases pass downward through the flue H, through the bottom oven-flues Gand G, and thence upward through the flue I to the eXitpipe. When it isdesired to heat the reservoir alone the dampers h and i are opened, soas to permit the heated gases to pass downward through the flues H and Nto the reservoir-flue M, and from the latter directly into the ascendingflue I. When both oven and reservoir are to be heated at one time, allof the dampers are closed, when the heated gases will pass down thesupplemental flue N into the sheet-flue M, and through the latter intothe descending flue H, after which said gases will pass beneath the ovenin the usual manner.

The construction shown gives to the operator such complete control overthe reservoir and oven as to enable either or both to be heated whendesired with speed and economy, and Without interference one with theother.

Having thus fully set forth the nature and merits of our invention, whatwe claim as new is- 1. In combination with the flues H and I, providedwith the openings h, h, z, and i, and dampers h, z", and i, thesupplemental flue N, communicating at its upper end with the topoven-flue F, and at its lower end with the reservoir sheet-flue M,substantially as and for the purpose specified.

2. In combination with the sheet-flues F and M, the flue H, providedwith the openings h and h and damper h, and the flue I, having theopenings 6 and i and the dampers i and i, substantially as and for thepurpose shown.

3. The sheet-flues F and M, vertical fines H, I, and N, communicatingopenings h, h, i, i, and a, and dampers h, i, and i, all combined tooperate in the manner and for the purpose substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our handsthis 11th day of March, 1875.
